Hey, i have a blade 150sx buggy and its giveing me engine trouble. Whenever i run over a snowpile or something or large bumps and let off the gas once i'm over it thte thing shuts down and i'm not sure why. I have changed the diaphram fuel regulator. And then the other night when i was testing it it shut down on the other side of my yard and would not start again because the battery did not have enough power to turn the motor over again. I'm not sure if anyones herd of a problem like this or even this buggy but yanno maybe someone might have some ideas.
